Booth perimeter calculation

The sales stand floor plan consists of squares and has an area of 48 m². What is the perimeter of these booths?
a. 34 m
b. 36 m
c. 40 m
d. 44 m

Final Answer:

o =  36 m

Step-by-step explanation:

$$\begin{gathered} S=48{\text{m}}^2 \\ n=4\cdot 3=12 \\ {S}_1=S/n=48/12=4 \\ {S}_1=a^2 \\ a=\sqrt{S_1}=\sqrt{4}=2\text{m} \\ o=18\cdot a=18\cdot 2=36\text{m} \end{gathered}$$
